Animate this original artwork as a refined five-second website hero media asset. Preserve the exact five-portrait speaker strip with fixed panel borders. Each adult person makes subtle natural independent micro movements: blink, slight head movement and gentle settling of existing hand gestures. Preserve faces, clothing and number of people. No lip-sync, speaking text, transitions or panel movement. Preserve original identities, proportions, palette and materials. Locked camera unless explicitly specified. No zoom, cuts, text, UI, new objects or distorted anatomy. Continuous restrained motion; begin and end near the same composition where physically plausible.
